boston. with everyone involved in this ghastly tragedy, what an appalling tragedy. that's all for us. we'll be back at midnight with the latest developments. now our team coverage continues live with anderson cooper in boston. >> piers, thank you very much. good evening, everyone. 10:00 here in boston. just a few blocks from the boston marathon finish line where two small bombs caused such terrible, terrible carnage investigation, just moments before a news conference at massachusetts general hospital. we'll bring that news conference live. three people now confirmed dead, including an 8-year-old boy. at least another 141 people wounded, many of them gravely wounded, bodies torn apart by ball bearings or something similar packed into those

explosive devices. there are a lot of late developments to tell you about. we have a team of correspondents covering this. i want to begin, though, by showing you just as it happened what words simply cannot fully describe. it is difficult to watch. it is very raw, and perhaps you've seen it already and may want to turn away and i would understand if you would. but raw is exactly what this story is right now. take a look. [ explosion ] >> a press conference is now just starting at massachusetts

general. let's listen in. >> what kind of injuries? >> a variety of injuries. probably the most common serious injuries are combined lower extremity injuries, meaning bone injuries, soft tissue and vascular issues. >> are you seeing some fractional type injuries? >> we're seeing a lot of shrapnel injuries, many involve the lower extremities. but shrapnel injuries can affect the entire body. >> doctor, please describe the scene when people were coming in, can you describe that? >> well, the first patient that came in was probably the most severe. we had three of the most critically ill patients come in the first 15 minutes. at that point, that did turn out to be the tip of the iceberg, so

i think everybody were prepared for that type of situation. so the hospital activated its incident command system. within about 5 to 10 minutes we had everything up and running. >> what are the ages of the victims? >> i don't have that information precisely. >> did you perform any amputations? >> yes, several. >> how? >> i can't tell you the total. >> can you tell us how many patients you've personally treated? have any of them been able to communicate with you what they saw, what they witnessed, what they went through? >> a number of patients have been able to talk. most of them, we kept it business only, to be honest. so in terms of just what affects their clinical condition precisely. so you probably know more than i do about what happened at the scene at this point. you had another question. >> how many have you been able to treat? >> the hospital has treated 29. i have operated on 6 so far today.

>> five patients were unidentified earlier. have you identified all of the patients? >> i don't know. i know some of them that came in have now been identified. >> there have been a lot of questions, doctor, about family members trying to reach their loved ones. have you had any indication from the patients that they've been able to reach their family members and been able to find them? >> some of them we have, some we haven't. some initially unidentified, it took a couple of hours to find family. i don't know of the 29 total, or the 11 particularly -- i'm sorry, 8 in critical condition, if we've been able to reach everybody. >> were these spectators or run sners >> i'm not sure. i have not taken care of any runners. but of the 29 people, there may have been runners. >> was there anything unusual

about the shrapnel? >> no. a lot of small metal debris. some people have asked already whether these were bbs or parts of bombs. i just don't think we're able to say. >> do you think the people in critical condition at this point are -- [ inaudible ] >> they're not looking okay, because that's not what critical condition means. so it's too early to say how everybody is. >> how long will this process continue, hours? >> a number of patients will require repeat operations tomorrow and serial operations over the next couple of days. a lot of the injuries are combined, boney and vascular injuries. and they have to be approached often times in kind of a step-wise fashion. >> were you seeing any shattered

eardrums? were they close to the explosion? >> we have seen at least one, which is not uncommon with blast injury. one of the things on the to-do list for me is to go right back around. it can be hard sometimes, particularly if people are being rushed to the operating room to get a good exam and repeat all of those exams. >> can you give us more information on ages, hometowns? >> no, i'm sorry i can't. i just don't have that information. the hospital may be able to give that later. >> can you talk about the amputees? you've had how many here? >> i can't tell you precisely right now. several. >> are 29 still at the hospital right now? >> i don't know. >> can you give us an age range? >> there were no pediatric patients is, somebody we design under 18. the oldest patient i took care of personally is 71. i think that's the oldest patient. >> what was the most horrific injury? you're a surgeon, but still.

>> it's just depressing that, you know, we take care of accidents all the time. it's just depressing that it's intentional. >> have you ever seen anything like this? >> the injuries are not other worldly. but no, i can't say i've seen this volume of patients come this quickly with this type of injury. >> can you elaborate by what you mean of not other worldly? it appears these devices may have been ied-like or crude in nature, but you say injuries not other worldly. can you explain that? >> any traumatic amputation is gruesome, but something we do see from time to time in the course of daily life, even outside of this type of event. >> i know you're trained for it, so does it kick in automatically? >> this is work. when this happens, we just go to work. >> doctor, you talked about injuries on a broad scale, can

you elaborate anymore on injuries? >> i'm hesitant to give you a rundown of each of the eight one by one. the dominant injury have been combined complex lower extremity injuries involving blood vessels, bone and soft tissue. [ inaudible ] >> one of my partners has been deployed to iraq and afghanistan, and i think has probably the most personal experience with these types of injuries. he's been here most of the night. but i haven't talked to him directly about how does this compare to what have you seen in the field? >> you said you were keeping it business for the most part, but were the patients, did any of them say anything that gave you a sense of what this experience is like for them? >> no, no. people, they want help in this kind of situation, and my

experience today is not unlike i guess other similar circumstances. people are pretty brave. it's a terrible thing, and most patient's attitude is do what you have to do. >> can you describe, if you look over here a little bit, can you describe what the scene was when it first happened? >> we just got a series of patients on stretchers. actually none of them with -- of the first wave, even some that were very seriously injured, none of the first few had breathing tubes in, so they were able to talk, even if they were in and out a little bit. again, the most -- when it kicked off, the most severe injuries were really these lower extremity injuries. and so we had, i think, three in about the first five or ten

minutes and that's when it became clear to us that it was going to be a busy day. >> ever seen anything like this before? >> like i said, the injuries individually are not completely outside the pale. but i've never seen this volume. >> there were six critical earlier, now there are eight. what changed? >> i'm not sure how they were classified or when. i think certainly there's some patients who may not have been classified critically the moment they hit the door. >> given the horror -- >> you said you were trained by israeli first responders. how did that help today? >> i was not trained by israeli disaster first responders. >> given the horror that you've seen, we've heard the governor say he's seen incredible signs of hope and help across this

region, and i -- we've heard reports of people saying even runners have called the hospital and offered to donate blood, that that's being coordinated. have you seen any of those bright signs? >> what i can say is within the hospital certainly. everybody rose to the occasion and we've had people who were out of town who flew back in here and made it back in within hours from nursing staff to ancillary staff, to operating room staff to specialists and really all of the different disciplines. we've had as much or more manpower or people power than we could use. i can't speak to the larger scenario, although i was asked by the hospital to mention to anyone willing to donate blood specifically, that it's appreciated. that right now we're okay. if they cannot forget the sentiment over the coming days to weeks, we are going to use a lot of blood with this incident and it will need to be

replenished. [ inaudible ] >> no, to my knowledge, they have not been, and they were not quarantined in the emergency department. >> were all nonelective surgeries put on hold? >> yeah, i can't tell you that. i would be surprised if all nonelective surgeries. for our general and emergency service, we did cancel our scheduled ki ed cases for tomor. >> did you say all victims have been identified? >> no, i don't have that information. >> do you know if all have reached their family members? >> again, i don't know. >> can we expect further information tonight? >> tomorrow. it looks like the next press conference will be tomorrow.

[ inaudible ] >> we'll tell you know where we are in the morning. thank you. >> do you know if everybody has been identified? >> i don't know. >> how much of this is a trying night for you and your colleagues? >> it's been a busy day. >> how many hours of surgeries did you do? >> pardon me? >> how many hours of surgeries, you said you had six surgeries. how many hours? >> i started doing surgery at 8:00 a.m., and i pretty much stopped to come talk to you. and i'm going to have to go back. >> can you spell your last name? >> that was the trauma surgeon peter fagan, describing the horrible injuries he's seen. eight critical patients at his

hospital alone. dr. sanjay gupta joining me now. what stands out to you? >> everyone has been talking about these lower limb injuries. this idea that there was a significant explosive force, but that it stayed close to the ground i think that keeps getting proven as we hear more and more descriptions. dr. fagan said he performed six operations himself. he said there were several amputations performed at his hospital, which is tough to think about in the context of this running event. he described the injuries to the legs as being boney, but also involving a lot of the soft tissue and vascular, meaning blood vessels being affected. the blood vessel injuries tend to be the most critical, because someone could be losing blood and blood blow to the limb. so those have to be addressed quickly. i'm sure that triage is ongoing.

>> sanjay, take a look at this video. what stands out when you see this video from a medical standpoint? >> when you watch that you see the explosion certainly happen, but look at obviously one runner falls, who may have just stumbled or may have had something happen to his ears, but there's not a significant blast to them in terms of moving them across the course there. i thought if you focus on that one thing, you can see -- get an idea of the focus and magny tutd of the impact. also, if you look at where the explosion comes from, just a few seconds or maybe 10, 15 seconds after that, you see some people running from that area. so no doubt this has been a -- obviously a significant explosion. but there were people in the area who were able to be running out. so they were aware and able to

run away from that source, anderson. >> and we're hearing at least 17 in critical condition, dozens more serious. this may be a dumb question, but what is the difference between critical and serious conditions? >> this may be a little bit of semantics, but critical condition does refer to someone who is in the intensive care unit, likely on a breathing sign and vital signs are going up and down a lot and need medications, possibly blood to maintain that. they're very worried about that. people in serious condition are one step underneath that. a little bit better than critical, but they can lapse into critical condition. they're certainly in very serious -- need a lot of monitoring from the medical staff, as well. so it may be a question of semantics at this point, anderson. >> and when you hear about ball

bearings being in these devices, obviously you get a real sense of just the horror these doctors are dealing with. i want to bring in ryan bourquer who ran in the marathon, saw the second explosion from his hotel room. ryan, thank you very much for being with us. first of all, how are you doing? >> i mean, it's hard to imagine what was out there, and basically when i came in, i was really happy that i finished the race. right after that, we were hanging out and basically talking. but then i heard what sounded like a cannon like you would hear at a stadium, and i thought that might have been at that time what was signaling the end of the race. but i saw people running and saw the second explosion. >> your mom had gone to the hotel room to watch the end of the race. >> that's right. we were on the fifth floor and it was a perfect vantage point for the finish of the race. but unfortunately the second

bombing, as well. >> we're showing some of the pictures that you took. you witnessed the second bombing. what did you see? >> i saw people running, then a flash and smoke. once i heard the second, i knew it was a bomb and i was scared. danielle, my girlfriend, said we should go straight into the bathroom. because if there were two, there might be three or four. we just wanted to get out of there as quickly as possible. >> how long did you stay in the bathroom for? >> probably five or seven minutes. it was great to hear the emergency crew right on the scene about -- less than a minute you heard sirens. you wanted to be sure it was safe, but by the time we got out, it was horrible. >> have you ever seen anything like this? >> i haven't seen anything like this at all. it was just people were all over the place. you know, bodies on the ground. there were people, you saw chest compressions and things you don't want to see.

>> i want to also bring in katie fox. i understand that you helped carry some little kids to safety. tell me what you experienced. >> okay. so we were at the forum, and we were actually working an event, and we were in and out all day. a couple of the people we were smoked cigarettes, so we were out front a lot. and five minutes before the bomb went off, we discovered a back door so we weren't in the front luckily. but we were standing around, and all of a sudden we just heard this crazy boom and the bar went black and it filled with smoke. for a second, everyone was like, what was that, and you heard people screaming, get down, get down, get out. so everybody rushed to the back of the restaurant where there was an alley. and at some point, there was

about 100 people more in a circle in the alley. and two little girls, i'm not sure where they came from, but two little girls were asking if it was a bad guy that did it. my cy our first reaction was to say no, it was fireworks, but somebody got hurt and we have to leave. it ended up being a woman out of town who had two little girls and a baby on her hip. so my sister's reaction was to pick up the little girl and start running. so we knew somebody about six blocks away, so we headed to our friend's house. >> how are you doing now, having witnessed something like this? >> me personally, i'm okay. i just -- i kind of found that i had to keep it together for my sister who actually -- she was running the event, and she had made tons of friends that day

with strangers. after the bomb went off, she ran back in to grab her bag and somebody she had befriended was missing a limb. so she kind of lost it. so i've kind of had to be a rock for her all day. so i don't think it's hit me yet. >> yeah. ryan, do you feel like it's real? often when you see these things, it seems so surreal. >> it still hasn't sunk in for me. i see running as a universal sport and you have people from all over the country, people from other countries coming in to run the race. i don't understand why anyone would want to do this. it's just a world sport, a world spirit and people come in and you have such a tragedy when someone does something like this. you never know whether marathons across the world are going to be safe again. >> have you been contacted by authorities? authorities want to talk to everybody who witnessed the

blast. >> my mom called the fbi at the airport trying to get information on people who had seen the blast, and my mom had some pictures on the explosion. so they talked to her. i think they're just trying to figure out who did it. it's such a crowded area, it's hard to see. >> ryan, i'm so glad you're okay. thank you for talking with us. >> my prayers and thought s everyone else. >> late word, that we've -- and katie, thank you very much as well. i wish you and your sister the best. we have late word of the atf who have sent all their personnel from boston to the scene. so that's just part of this massive investigation that will be going on for many days. late word that police are on the lookout for someone with a possible connection to the bombing, a possible. sort of a person of interest. they're not saying it's a

suspect. that news the always comes with caution. early leads may well be false leads. there's simply so much information authorities have to deal with right now. but with that in mind, john king has been talking to his sources and joins us now. john, what are you hearing from your sources, both here in boston and in washington? >> i'll circle back to that be on the lookout notice that went out in a moment. i want to bring you the latest. i just had a communication with a law enforcement force in boston tonight. here's the information, we have a number of active leads and some good early progress in the forensics analysis. but that same source went on to say but no identified suspects to my knowledge. this source says personally knows of two explosive devices and several suspected devices. he said he saw no additional reporting from law enforcement officials of any additional

confirmed devices beyond the two. but two confirmed devices. i asked him, because the fbi special agent in charge at the briefing tonight called this a criminal investigation and said "potential terrorism investigation." fbi and other federal officials? washington labeled it earlier terrorism. so i asked this source if they were dialing back and the source said "there's a clear effort here to be cautious. te vent speaks for itself, but we have a lot to learn." the next briefing is scheduled for the morning. to the alert, police put out what is called a bolo, a be on the lookout notice for a dark-skinned, possibly black male who was seen trying to get into a restricted area about five minutes before the first explosion. when turned away, apparently according to this alert, this person, who they only identified

as a be on the lookout for, said he had a foreign accent, looked away, put a hood on and left the scene. so that is one alert, a be on the lookout alert. and you heard commissioner davis at that briefing tonight, there is someone at the women's hospital, a saudi national, who is identified as a person of interest, but the boston police commissioner pushed back, saying that person is not a suspect, just one of several people we're told who are being questioned about what they know, where they were at the time of the explosion. but the police commissioner reporting back at some reporting that had called that person a suspect. anderson? >> and we're trying to be very careful and cautious in what we're reporting. brian todd joins me here in boston. i know you've been working your sources. i know you spoke to the police commissioner. what are you hearing tonight?

>> the police commissioner said at least two devices were involved, possibly a third. he pushed back on the idea that this person of interest at the hospital was some kind of a suspect. told me there are no official suspects in custody right now. i asked him about surveillance video of the scene. he said there was surveillance video, they're trying to figure out where the cameras were, but also working with the fbi to bring in as much video evidence from media outlets that were there. he said those were cameras that were there, as well. working with the fbi to gather as much of that footage as possible to see what they can find out. so between surveillance and media cameras, they're working those angles, they will. three fatalities were confirmed, injuries are severe. we know that several amputations took place as a result of injuries. and he has, again, pushing back on the idea that the person at the woman's hospital is a suspect. no official suspect in custody right now. >> john, even if all the video

cameras that are around, and all the cell phone cameras that people had, we're still talking of an area where there were thousands of people. so that will take time to go through. >> when the source tell me the early forensics, that there was some progress, he was talking about the debris collected from the crime scene. but you're absolutely right. i'm familiar with the neighborhood. i grew up there, and when i'm in boston, i go to that area all the time. you know it as a busy shopping, busy tourist, and busy business environment. so there are so many surveillance cameras. so by the city, some by private institutions, including the businesses. so there will be hundreds of angles they have to look through. those are just the cameras in place. obviously we know so many individuals have videos carrying their phones. so the investigation will take forever. and the crowd complicates. what they're looking for is nip

right in that area and left just before the explosions, as opposed to the chaos that happens just after the explosions. >> and john, are they saying, and brian maybe you heard this, as well. have they said publicly if they know exactly where the devices were? you know, in a garbage can, a mailbox or -- do they know? >> i was told by one source earlier the suspicion, and i want to emphasize the suspicion. they will look through the debris. and the bomb experts can figure out if there's a mailbox been broken up or a garbage can, they can look for explosive materials inside it. i was told earlier they suspect a mailbox or garbage pale but did not have definitive information. >> what we are hearing from the nature of the injuries is they believe it was a device close to the ground. >> and not a sophisticated device.

if they're pulling ball bearings out of people's legs, this was -- the police commissioner said they're looking at several locations, he said they're getting reports of suspicious packages all over the place. they have to follow up all those leads, as well. so that takes them to all sorts of locations around the city. a lot of those are going to be false leads. >> brian, appreciate the reporting, john king, as well. joining us is massachusetts homeland security adviserer and cnn contributor fran townsend is with us. also with us, cnn contributor and former fbi assistant director tom fuentas. fran, i know you consider to work your sources. there's one person that authorities are talking to, and

again, we want to urge caution how we approach that information. but what is the latest you're hearing? >> anderson, this is an individual who had a leg wound, is this the hospital, is a saudi national. they were very clear to say to me this person is not under arrest, and quite frankly, while we know about this one, i suspect that there are other persons of interest. so we shouldn't read too much into that. in the early goings of any investigation, your going to find there are plenty of people who come up on an investigator's screen. some will shake out, that is they will be spoken to and not further followed up with. and on the other hand, some may develop into suspects. they're looking at all the forensics. the video surveillance from the cameras. they're looking at forensics from the streets, from this crime scene, what can they learn about the construction of these bombs, the type of explosives used. and is there a signature, is there dna evidence from the

potential bomber that may have been left behind? so all those things are the kind of clues they're going to try and piece together. >> julia, from a law enforcement perspective, it's critical to make sure there are no other devices out there. >> right. that would be primary. i don't think we can underestimate how good it was that there was critical care right there because of the marathon. that probably saved lives. the police officers responding, knowing this would be a crime scene. so talking to people in state and local government, a lot of the evidence was probably preserved. those are lessons from 9/11. so that's good news going forward. >> again, it's important to point out, god bless all those first responders. we've seen the images of them running to, rushing forward, even knowing after that first explosion, it's possible there could be a secondary explosion. >> that is the sort of post 9/11 training that's gone on in the federal government for the last

11, 12 years. what was essential in this regard was getting these runners away from the finish line. that someone, whatever it was, that some message went out, pulled them off that street, about a half mile down the street. and pulled them over here to commonwealth avenue. >> thousands of runners were able to avoid that. we're just a few blocks from the end of the finish line. we talked earlier, and this finish line, which was kind of a controlled area over the last several days. again, we don't want to speculate, but you would believe that whatever devices were brought in, were brought in today. >> yes. it was such a secure site. i did boston marathon security, and just knowing how we secured the area. this area has been secure for the last 48, 72 hours. but when the marathon starts, that's when you have 25,000

runners coming from either family and friends, the first responders. it becomes more chaotic, controlled chaos. that is when someone can come in undetected. that is why it's important that you may have something on your i phone, you may see something that you don't know, and let us see it. i just know how we secured this area, but look, a marathon is a spectator sport. thousands of people are here, and that's what makes it fun. what we do know is, we'll be here again next year and hopefully it will be safer. i really think the city will bounce back very quickly. >> no doubt about it. a strong city. tom, again from a law enforcement back ground, if that is in fact the case, that this was a device or devices which were brought in today, that would help law enforcement in terms of narrowing down the window that they have to search for a video of when these devices could have been placed. >> right, anderson. i think the window would be very narrow any way, because a person

would not want to leave a device there and figure it's going to be in tact for 12 or 24 hours. they would pretty much assume that any backpack or package left on the ground is going to be picked up and examined within a short period of time. so it will be pretty much expected that a person would bring the device to the scene and have it detonated a short time later to avoid having it picked up by the authorities. i would like to add, much speculation has been made about the device and whether it has ball bearings or what type of shrapnel. i was an assistant commander at the atlanta summer olympics in 1996 and was on duty as the assistant duty the night of the centennial park bombing. that particular bomb, in a knapsack or backpack, had the explosive device, like a pipe bomb, and above it, a plastic food container filled with roofing nailed. so when it exploded, it sent

those nails airborne, killing one woman and one person died of a heart attack. so it sounds similar to the bomb today where you have metal maybe placed in the container around the explosive to create that shrapnel that wounded so many people in the legs. >> and tom, i don't want to give anybody out there ideas, but just in terms of the level of sophistication or knowledge required to make such a device, where is it? what is it? >> it's not very sophisticated at all. when i was in atlanta that summer, we had people being picked up almost every day with pipe bombs they made themselves in the back of their pickup truck and they were on their way to go fishing to throw the bombs in the water and scoop up the fish. it seemed like everybody in georgia knew how to make a pipe bomb and use it for purposes like that.

so it's not a highly sophisticated bomb. the tools used to build it would be readily available and it wouldn't be that difficult to do. i would like to make another point, anderson. there's been much discussing about isn't this terrorism, it's criminal. first of all, terrorism is a crime. so it's automatically a criminal case. but secondly, if it was not terrorism, the fbi would not be in charge. it would be boston pd run thing case. so it's clear the authorities are absolutely clear. this is a terrorism investigation. it's a terrorism case. and one of the politicians are worried about it sounds bad, we don't want to say that. we've got to make it sound softer. it's only a crime. that's fine. but make no mistake, this is a terrorism investigation. that's why the fbi is running it. >> i think the point here is the motive does not matter right now. it was clearly a terror act.

terrorism has on the defined in court and whether it's domestic or international. whether someone calls it one thing or other is irrelevant at this stage. >> let's hold it right there. stay with us. just back, we're just passed the bot testimony of the hour. for those just joining us here and overseas on cnn international, i want to recap what we know at this hour. it's changing by the minute. tonight, a massive multiagency investigation is under way after two bombs exploded just 12 seconds apart near copley scare. that area now a crime scene. at least three people confirmed dead, including an 8-year-old boy. 141 people wound, 17 in critical condition clinging to life. so far no claims of

responsibility of this terror attack. a source telling cnn the two bombs that exploded were small with no signs of high grade explosive tematerial. police found and defused one other explosive device. we started to show you this tape earlier. this is how it unfolded in real time. this is the reality of what happened today here in boston. [ explosion ] [ second explosion ] [ screaming ]

>> we just had an attack. [ sirens ] >> oh, my god. oh, my god. oh, my god.

oh, my god. [ sirens ] [ sirens continue ] >> let's go, let's go.

>> truly horrifying day for everyone who witnessed it up close. "the boston globe"'s david able saw it firsthand and joinings me now. david, i understand you were about ten feet away from one explosion. >> yeah, thank you. i'm definitely a little shaken up. it was -- it was probably the most frightening day of my life. >> explain, if you can, what you saw, what you heard, what it was like. >> so i was standing on the center of the finish line taking video of runners as they were coming in. it was an incredibly wonderful moment, a kind of idyllic moment watching the runners raise their hands in joy and jubilation, as they were finally making it across the finish line. just as i was kind of taking all of this footage, there was this

massive boom. the ground shuttered, and i saw a large plume of white smoke. it was quite disorienting, and at first, it was unclear what happened, whether there was a machine that malfunctioned, whether there was a gas explosion, whether it was celebratory cannon fire. all the things that run through our mind when we hear something we don't expect. but as soon as the smoke cleared, i could see the blood. i could see the broken glass. i could see the mangled limbs. i could see people crying out for help. >> and then the second explosion. >> and then, right, and so i guess in that -- in those

moments while the smoke was clearing and i was trying to process what happened, there was the second explosion. i described it as the feeling of when the second tower -- when the second plane hit the other to y tower in the world trade center and immediately anyone who was there knew that this was not a machinery malfunctiomalfunctions was an attack. >> when you realized this is not a generator blowing, that this is an attack, what did you do? >> you know -- [ lost connection ] >> i think we lost david. we'll try to get reconnection with him. he was just describing what he saw at the second explosion, and i'll ask him what he did afterward. i want to bring in jason

carroll, who is at brigham and women's hospital. jas jason, the scene there, what are you hearing from doctor there is? what's the latest? >> reporter: let me just bring in one of the doctors here. this is dr. ron walls. so much has been said about the types of injuries that we've been seeing, you've been experiencing here at the hospital. can you give us the latest in terms of what you have? you have 28 patients that's up to 31 >> that's right. we have 31 patients. two would be considered very critical. we've had a total of nine that have gone to the operating room. so i've had surgery in all of those cases, major surgery, then we have the remainder that takes you to the rest of the 31. >> can you describe the extend of the injuries? we've been hearing bone injuries, tissue injuries. >> the worst of the injuries have been injuries to the legs.

there's been a lot of damage, a lot of blast effects from these type of explosions, so a lot of injury to the muscle, the skin, the bones are broken, those sorts of injuries. the shrapnel has been a minor issue. there are little bits in some of the patients. just ambient things thrown around in the blast. >> that's good information there. also, two of your patients is critical condition? >> two are critical, and that first 24 hour period there can be a lot of change. we have two patients that we have classified as critical. >> one of your younger patients was 3 years old and that patient was then transferred? >> our youngest patient was 16 years old, but the -- we had one child of 3 who was brought in initially and we immediately retriaged that patient to children's hospital right beside us. >> doctor, one of the nurses

that came out described this as being a very emotional, trying day. i know you guys are trained for this, but does any of your training prepare you for what you saw today? >> i don't know that you can ever prepare for something like this, but if you can, we were. so this is what we do. every day we take care of patients with bad trauma, and we have industrialed for this type of event city wide and in our hospital over and over again. the whole time hoping we would never have to use it, but we were ready. >> i spoke to one of the attendants who came out and said it was droves and droves of ambulances coming in. he said six at a time at one point. i'm wondering when the first injuries started to come in, when did you get an idea of the extent of what you were dealing with here? >> the first couple of people came in, and the second or third patient that arrived before we had formal notification of the numbers or detailed involved, about the second or third patient had a very, very bad

injury to the lower extremities, so we knew this was a big thing. >> the hospital is still on lockdown, i want to point that out, as well. have they given you any indication why the hospital has remained on lockdown? we've got s.w.a.t. out here, members of the fbi here, as well. >> we eastern not on lockdown. we're open. we have i guess what i guess is heightened security. they're just being careful about people who come in have identification, are patients or family members, clinicians and workers. so we're open. we're just in heightened security. >> one of our anchors, dr. sanjay gupta has a question for you. i ask hear the question, the doctor cannot. so i'm going to have dr. sanjay gupta give me the question and i'll ask a few. >> i wondered if you could ask, he said there were nine operations performed. besides the lower limb types of

operations, what other types of injuries are requiring surgery? >> very interesting. dr. sanjay gupta mentioned the nine patients who required surgery to the lower limbs. any idea what other types of injuries that you're seeing that require surgery? >> yes, most of them were orthopedic injuries and injuries of muscle, bone and tissue. we did have one patient who had a lot of sort of head and facial injury that required surgery. but most of the blast impact came lower down. so most of the injuries were leg injuries.sanjay, i know you hea that. any other questions sanjay or anderson? >> i don't have any questions for the doctor. we'll leave it at that. jason carol, i appreciate it very much. cnn executive producer was here watching his brother run the marathon. we'll talk to him just shortly

when i made the turn, it was like the first pop, boom. and then another one, boom! and then another one, boom. it was just one big cloud of smoke. this is really, really bad. >> well, we have new information just now, the number of injured has risen to 144. matt was here watch his brother running the marathon. >> we were close to the finish line, excited to see my brother finish. but 1,000 people on either side of it, and we heard the first explosion about 100 yards away. big plume of white smoke. >> did you why any idea what was that? >> we didn't know what it was, but 10 seconds later, 20 yards the second one went off. >> could you feel it?

>> i definitely felt it in my ear. >> did it have a spectacular smell or odor? >> no. i didn't see fire, i just saw smoke exploding up. it looked like it was coming from the sidewalk almost. so i thought it was a manhole or something like that. but a lot of people knew it was a bomb and scrambled away. >> so you took off? >> everyone took off. it was like mass panic in a way. i sort of got pushed with a bunch of other people into another building. and we didn't know if there was a third bomb. but i was able to find my family again and we went back out the building. and then up into an entryway where we were able to look down on the carnage and saw people being treated on the street there. >> was your brother diverted? >> he was about a mile away and he got diverted. he had a cell phone, but they

weren't working. my other brother and his wife and three kids were closer to the explosion. my brother's son asked him, who was that noise? my brother knew it was a bomb, grabbed the kids and went the other way. >> unbelievable. so glad you're okay. thanks so much for talking about it. so many people seeing it from different angles. we're trying to piece it together as best we can. fran joins me, as well as tom. tom, in terms of what happens overnight, where the investigation is now, juliette earlier was saying critical right now that law enforcement just wants to make sure there are no other devices still out there. what are the other arms of this investigation? >> the forensic work will continue. it's going to be very difficult, i'm sure they brought lights out to help them do the crime scene. and actually both crime scenes where both bombs went off.

as far as the rest of the work, there are a number of records that they're going to need to obtain, seasons that have to be written, prepared, types, ready to give to businesses for telephone records, internet records, the cell tower, how many phones were hitting off of the cell phone towers that were in close promiseproximity. so work will be going on around the clock. any identity of international perps of interest or others, that work would be daytime ov overseas, so that work will be continuing in other countries if there are leads that are led to request that information overseas. so there will be a tremendous amount of work going on around the clock indefinitely from this point. >> and fran, just from an investigation standpoint, because this was such an international event, tens of thousands of people coming from

all over the world, tracking people who are not from this area, i mean, coming in by plane and train, that's going to be very difficult. >> it is, anderson. let's remember, we understand that this is an international event. there are people from around the world who are running in it. so every country who had citizens coming here to run will have reached -- those countries will reach to their ambassadors. the ambassadors will be trying to gather information on potential victims in this country, who were at that event running. and so it works both ways. we'll be looking for the assistants of our foreign partners around the world. the international citizens who are our guests at the boston marathon who may have been injured or hurt, their home countries will be trying to get information to help them. >> john king, you know this city very well. from the sources that you've been talking to, how optimistic do they sound to you? >> the sources are optimistic

that eventually they will get there, anderson. but tonight what is not being said is probably as important as what is being said. that's because there are more questions than answers. when it comes to the motive question, people are divided. obviously as fran noted the, this is a big international event. if you were an international terrorist group, this could be your target. but they're being careful not to speculate about a motive. the subway station underneath will be closed tomorrow, the governor saying most of the area will be affected tomorrow because they understand because of the chaos, because of the type of explosive devices, because of the scattered evidence, if you will, they're going to stay at that law enforcement sources say to grab every possible piece of evidence at that scene. >> well, appreciate all your

reporting today, fran, as well. when we come back, we'll update you with all the latest information and how you can locate loved ones if you have not been able to contact them so far. we'll be right back.
